Electronic grade polycrystalline silicon of purity 99.999999999% put into mass production in China recently. After a series of test, trial and confirmation, recent batch of high purity silicon material that is for integrated circuit already exported to South Korea. They also supply to some wafer domestic manufacturer. This mean silicon material that China enterprise process reach international standard. This is also first time China enterprise export high purity silicon material to international market.
Electronic grade polycrystalline silicon is key basis material for integrated circuit. Before polycrystalline silicon for integrated circuit reply on importing in China market. Electronic grade polycrystalline silicon has the highest purity of polycrystalline silicon powder. Compared to solar grade polycrystalline electronic grade one must reach 99.999999999%.
